FLOAT-VALVE.

Specification of Letters Patent.

Patented Nov. 21, 1905 Application filed October 15, 1903. RenewedOctober 14, 1905. Serial No. 282,809.

To all whmn itvveay concern:

Be it known that I, EDWIN P. CLARY, a citizen of the United States,residing at Dilley, in the county of Frio and State of Texas, haveinvented a new and useful Float-Valve, of which the following is aspecification.

My invention relates to float-valves designed especially for usein'connection with stockwatering tanks, and has for its objects toproduce a comparatively simple inexpensive device of this characterwhich will automatically out ofl the supply of water when the tank isfilled and one in which the parts of the valve-chamber may be readilydisconnected and the valve removed for purposes of cleaning orrepairing.

To these ends the invention comprises the novel features of constructionand combina tion of parts-more fully hereinafter described.

'In the accompanying drawings, Figure 1 is 1 a vertical sectionalelevation showing a portion of a tank having a valve constructed inaccordance with my invention applied there- Fig. 2 is a detail sideelevation of the valve.

Referring to the drawings, 10 designates a stock-watering tank of theusual or any appropriate construction and material and having leadingthereinto through its bottom a supply-pipe 11, which discharges into avalvechamber 12, comprising a'pair of end members or heads 13 1 1 and atubular body portion or shell 15.

The end members 13 14:, which are of polygonal form in cross-section toadapt them for manipulation by a wrench, are tapped, respectively, intothe ends of the shell 15, the lower member 13 being threaded onto theupper end of the pipe 11 for coupling the latter with the tank, whilethe upper member 14 has an interior annular flange or collar 15, uponwhich is formed a valve-seat 16, against which a ball-valve, of rubberor other suitable material, normally rests for cutting off the supply ofwater through the casing 12 to the tank. This valve is carried at thelower end of a vertically-movable stem 18, provided at its upper endwith a float 19, which when raised by the water in the tank maintainsthe valve in closed position.

The valve-stem is housed within a vertical stand-pipe 20, tapped at itslower end into the upper end member 14, the flange 15 of which forms astop for said stand-pipe and provided adjacent to said end member with aplurality of transverse openings 21, constituting passages for the waterfrom the casing to the tank when the valve is opened. It is to be notedthat this stand-pipe is of such length relative to the stem 18 that itwill serve as a stop to limit the downward movement of the float underthe influence of an ebb of water in the tank to thus prevent the valveseating upon and closing the upper end of the pipe 11, it being apparentthat when the waterrises to its normal level the float will rise withit, thus actuating the valve to automatically cut off the supply ofwater; also, that when the valve thus rises and strikes the valve-seatthe latter will be greatly reinforced and possibility of breakageprevented by the lower end of the stand-pipe abutting upon thevalve-seat.

Disposed between the lower member 13 and the adjacent inner face of thetank-wall is a packing gasket or washer 22, while a member or washer 23is likewise disposed between the outer face of the wall and the adjacentend of a coupling-elbow 24, provided in the pipe 11. It is apparent thatunder this arrangement when the member 13 is properly operated fordrawing the pipe 11 upward the washers 22 23 will be clamped tightlyagainst the adjacent faces of the wall, thus insuring a securewater-tight jointand, furthermore, renderingthe connection of the pipewith the tank firm and secure.

It is obvious that from the foregoing I produce a simple efficientdevice admirably adapted for the attainment of the ends in view and onein which the various parts of the valvecasing may be readilydisconnected for purposes of cleaning or to permit removal of the valvefor repair, and this without disturbing the connection between the tankand its supply-pipe. The position of the stand-pipe is regulated bythe'fiange or collar 15, which also constitutes a valve-seat. It is tobe noted, however, that should the contingency at any time arise thepipe may be readily disconnected from the tank merely by unscrewing themember or nut 13. In attaining these ends it is to be understood thatminor changes in the details of construction herein set forth may beresorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed is The combination,with a stock watering tank, of means for regulating the admission ofwater into said tank, said means comprising a cylindrical casing, alower end member threaded into said casing, an inlet-pipe ex- IIO flangeforming the valve-seat in the upper end member and said stand-pipe beingalso adapted to support the float when the latter is in a 5 loweredposition. v

In testimony that I claim the foregoing as my oWn I have hereto afiixedmy signature in the presence of tWo Witnesses.
